Question 3

A building has 29,000 ft ² of floor space. When an addition of 6,000 ft ² is built, what is the percent increase in floor space? Round to the nearest tenth of a percent if necessary.

Accepted Answer

The percent increase is calculated by dividing the increase in floor space (6,000 ft²) by the original floor space (29,000 ft²) and then multiplying by 100. This gives (6,000 / 29,000) * 100 = 20.7%.

Question 4

What percent of 4,260 ft is 852 yd? Round to the nearest tenth of a percent if necessary.

Accepted Answer

1 yard = 3 feet
Therefore, 852 yards = 2,556 feet
To find the percentage, we divide 2,556 by 4,260 and multiply by 100:
(2,556/4,260) x 100 = 60%
Therefore, the answer is E) 60%.

Question 6

On a cross-country trip, 1.1 h were flown under VFR (visual flight rules) and 0.9 h were flown under IFR (instrument flight rules). What percent of the trip was flown under IFR? Round to the nearest tenth of a percent if necessary.

Accepted Answer

The total flight time is 1.1 + 0.9 = 2.0 hours. The IFR portion is 0.9 hours. To find the percentage of the trip flown under IFR, divide 0.9 by 2.0 and multiply by 100: (0.9 / 2.0) * 100 = 45.0%.

Question 7

What percent of 0.600 grain is 0.250 grain? Round to the nearest tenth of a percent if necessary.

Accepted Answer

To find the percentage, divide the smaller quantity by the larger quantity and multiply by 100. 
Percentage = (0.250/0.600) x 100 = 41.7% (rounded to the tenths place)

Question 11

What percent of $\frac { 1 } { 4 }$ is $\frac { 1 } { 14 }$ ? Round to the nearest tenth of a percent when necessary.

Accepted Answer

To find what percent $\frac{1}{14}$ is of $\frac{1}{4}$, you divide $\frac{1}{14}$ by $\frac{1}{4}$ and then multiply by 100 to convert to a percentage. $\frac{1}{14} ÷ \frac{1}{4} = \frac{1}{14} × \frac{4}{1} = \frac{4}{14} = \frac{2}{7}$. Converting $\frac{2}{7}$ to a percentage: $\frac{2}{7} × 100 ≈ 28.6\%$.

Question 12

You need 0.6% of 1,000 mL. How many mL do you need?

Accepted Answer

To find 0.6% of 1,000 mL, multiply 1,000 by 0.006 (0.6/100), which equals 6 mL.

Question 13

A welder needs to complete 130 welds. If 96 have been completed so far, what is the percentage completed? Round to the nearest tenth of a percent if necessary.

Accepted Answer

To find the percentage completed, divide the number of welds completed by the total number of welds and then multiply by 100. So, $ \frac{96}{130} \times 100 = 73.8\%$.

Question 14

The value of Caroline's house decreased from $75,500 to $69,500 when the area's major employer closed the local plant and moved to another state. Find the percent decrease in the value of her house. Round to the nearest tenth of a percent if necessary.

Accepted Answer

The percent decrease is (75,500 - 69,500) / 75,500 * 100 = 6,000 / 75,500 * 100 = 8%.

Question 15

What percent of $753.33 is $226?

Accepted Answer

To find out what percentage of $753.33 is $226, we need to divide $226 by $753.33 and then multiply the result by 100 to get the percentage.

$$\frac{226}{753.33} \cdot 100 \approx 30\%$$

Therefore, the answer is option C.

Question 16

During manufacturing, the pressure in a hydraulic line increases from 50 lb/in ² to 60 lb/in ². What is the percent increase in pressure? Round to the nearest tenth of a percent if necessary.

Accepted Answer

The percent increase in pressure is calculated as the difference in pressure divided by the original pressure, then multiplied by 100. So, $\frac{60 - 50}{50} \times 100 = 20\%$.

Question 17

The number 753.5 is 5.5% of what number?

Question 18

Due to wage concessions, Bill's hourly wages dropped from $19.50 to $16.00. Find the percent decrease in his wages. Round to the nearest tenth of a percent if necessary.

Accepted Answer

The percent decrease in Bill's wages is calculated by the formula: [(Old Wage - New Wage) / Old Wage] * 100. Substituting the given values: [(19.50 - 16.00) / 19.50] * 100 = 3.50 / 19.50 * 100 = 17.9%.

Question 19

Identify the rate ( R ), the base ( B ), and the part ( P ), in the statement. Do not solve the problem. $33 \frac { 1 } { 3 } \% \text { of } 360 \text { is } 120$

Accepted Answer

The base is the whole amount, which is 360. The part is the portion of the base, which is 120. The rate is the percentage, which is $33 \frac { 1 } { 3 } \%$.

Question 20

$35 is 3.5% of what amount?

Accepted Answer

Let x be the amount we are looking for.

We can set up the following proportion:

35/x = 3.5/100

To solve for x, we can cross-multiply:

3.5x = 35 * 100

3.5x = 3500

x = 3500/3.5

x = $1,000

Therefore, $35 is 3.5% of $1,000.
